AV signal transmission unit No name TR-1DL*P2 video transformer, model TR-1DL*P2

AV signal transmission unit No name TR-1DL*P2 is a video transformer designed to transmit and condition audio-video signals between devices. It provides galvanic isolation and impedance matching for video lines, helping to reduce interference and maintain signal integrity in CCTV, monitoring and AV distribution systems. The unit is intended as a passive component within installation panels or inline connections where stable video signal transfer is required.

Advantages

The TR-1DL*P2 video transformer offers reliable passive signal adaptation without the need for external power, reducing points of failure. Its simple construction ensures predictable transmission characteristics and effective reduction of ground loop noise when used for galvanic isolation. The compact form factor and standardized connection interfaces simplify integration into existing AV racks or junction boxes.

Suitable for

• CCTV camera signal isolation and distribution
• Video monitoring systems in commercial or residential installations
• AV signal routing and line matching in control rooms and rack systems
• Temporary installations and maintenance setups requiring quick isolation

Key specifications

• Function: passive video transformer for AV signal transmission
• Purpose: galvanic isolation and impedance matching of video lines
• Signal types supported: composite video and compatible CVBS-type signals
• Power: passive operation, no external power supply required
• Form factor: compact module suitable for rack or junction box mounting
• Connections: standardized video input and output terminals for easy integration

How to use

Install the TR-1DL*P2 inline between the video source and the receiving device, connecting video output to the transformer's input and the transformer's output to the monitor, DVR or routing equipment. Ensure secure and correct polarity connections and mount the unit in a dry, ventilated location away from strong electromagnetic interference sources. No power connection is required; after installation, verify signal presence and image quality at the receiving end and adjust cabling or grounding as needed.

Usage recommendations

For best results, use the video transformer to isolate ground loops and to match cable impedances over longer runs. Verify compatibility with the specific video signal format in your system and test each channel after installation. If persistent interference persists, inspect cable shielding and grounding at both ends before replacing components.
